feel like crap!!!!!

This is my 2nd pregnancy back to back (NOT as close as I wanted) but god works in mysterious ways. So my son will be 1 in August and I'm due in October. No matter what I do how much I rest I constantly feel like crap. I can't even stand over the stove and make my family breakfast without feeling like I have to pass out. I have ZERO ENERGY, I'm am so tired!!! A teething baby, a husband who I have to treat like a child a 12 yr old who plays food ball and a 17 yr old away at school. I just wanna lay down and sleep for a week!!!! I hope I'm not the only who feels this way!!!💤💤💤💤
